To all whom it may concern:

Be it known that I, CLARENCE I. B. HEN- NING, a citizen of the United States, and a resident of Wilmington, in the count of 5 New Castle, and State of Delaware, liave inventetl a certain new and useful Priming Mixture for Propeilent Explosives, of which the following is s s ecification.

his invention to ates to priming or ignit- 39 ing mixtures for pro ellant explosives, and comprises a priming c arge containing as an essential constituent hexanitrocliphenylamine.

I have found that hexanitrodiphenylamine 35 has properties which make it; specially valuable as a constituent of primers for modern progressive-burning smokeless powders, the other ingredients of the priming mixture comprising, for example, potassium chlorate 20 and antimony sulphide.

Compositions made uccordinq' to my in vention may be illustrated by the following examples: I
